JOHNSON MACHINE WORKS, INC.

Johnson Machine Works, Inc. specializes in the precision fabrication and modification of heavy-duty structural metal components for critical infrastructure projects, with deep expertise in welded steel assemblies for hydraulic and marine applications. The company delivers custom-fabricated stop logs, bulkheads, miter gates, and service gates for U.S. Army Corps of Engineers projects, performing certified welding inspections on fracture-critical welds and executing complex modifications to existing hydraulic structures. Their technical capabilities span fabricated structural metal manufacturing, machine shop operations for precision components like jam nuts, and the assembly of large-scale lock and dam hardware, demonstrating proficiency in ASTM and AWS welding standards, dimensional tolerancing, and field-ready fabrication for harsh environmental conditions. Their ability to respond to urgent modifications on mission-critical water control systems underscores a strong focus on reliability, regulatory compliance, and on-site adaptability. The contractor maintains a consistent and long-standing relationship with the Department of Defense, particularly through the U.S. Army Corps of Engineers, Huntington District, delivering mission-critical metal fabrication and inspection services for flood control, navigation, and dam safety infrastructure. Their work is exclusively focused on defense and civil works projects involving water resource management systems, indicating a trusted role in sustaining federal infrastructure resilience. Their primary industry focus lies in fabricated structural metal manufacturing and machine shop services, where they produce custom steel components for hydraulic structures, spillway systems, and lock mechanisms. This positions them as a niche supplier to federal civil works programs requiring engineered metal solutions for dam, levee, and navigation infrastructure, with secondary expertise in miscellaneous fabricated metal products for specialized mechanical parts. Johnson Machine Works, Inc. is a small, locally based manufacturer headquartered in Chariton, Iowa, operating as a 2L entity with no federal certifications on record. Their geographic proximity to Midwest water infrastructure projects supports rapid response and on-site collaboration, reinforcing their role as a reliable, hands-on fabricator for the federal government’s civil engineering and defense infrastructure needs.
